Animoto.com/Magiosto.com like video marketplace - Customization

Hi, I sell gigs on some websites like fiverr.com. I have After Effects templates i created, People send me their wedding, b-day photos etc... i change them with place holder images and texts, i render video and send videos with their photos and texts. But you can make such things online in seconds on; [login to view URL] and [login to view URL] (please check out the websites first) You upload your photos and enter your texts, it automaticly creates video for you in seconds... I'm currently working on a project to have video marketplace. I have a wordpress theme and it needs customizations. I have my own Adobe After Effects templates. (already prepared nice slide-shows with image placeholders) These templates CAN BE CONVERTED to any demanded file type for you guys can be able to write scripts. And run it on the server. Flowchart will be like this for USERS: Select your image or/and video --> Select a theme (from the website) --> Add(optional) Music --> Create your own video --> Share/download. Thank you
